The world's data centres, power and AI compute, country by country
Data centres per million people
Ireland: 16.05 per million, 5th of 214. Nauru is highest at 83.16 per million.
How to read this. Sites mapped in OpenStreetMap as data centres (telecom=data_center, or a building tagged data_center), duplicates removed, per million people. Counts what volunteers have mapped: colocation halls and big campuses are well covered, small server rooms and some hyperscaler sites are not. Neither higher nor lower is better in itself.
Why it matters. How dense each country's data-centre estate is, on one method for every country.
